Question

Sounds simple enough, but I’m feeling quite stupid today.

If I have an array like this:

$defined_vars = array(
    '{POST_TITLE}' => $item['post']['name'], 
    '{POST_LINK}' => $item['post']['link'], 
    '{TOPIC_TITLE}' => $item['topic']['name'], 
    '{TOPIC_LINK}' => $item['topic']['link'], 
    '{MEMBERNAME}' => $txt['by'] . ' <strong>' . $item['membername'] . '</strong>', 
    '{POST_TIME}' => $item['time'], 
    '{VIEWS}' => $txt['attach_viewed'] . ' ' . $item['file']['downloads'] . ' ' . $txt['attach_times'],
    '{FILENAME}' => $item['file']['name'],
    '{FILENAME_LINK}' => '<a href="' . $item['file']['href'] . '">' . $item['file']['name'] . '</a>',
    '{FILESIZE}' => $item['file']['size'],
    '{DIMENSIONS}' => $item['file']['image']['width'] 'x' $item['file']['image']['height'],
);

And a String like this:

$string = '<div class="largetext centertext">{POST_LINK}</div><div class="smalltext centertext">{MEMBERNAME}</div><div class="floatright smalltext dp_paddingright">{POST_TIME}</div><div class="dp_paddingleft smalltext">{VIEWS}</div>';

I need it to be replaced with the values of those keys. Is that possible to do? Perhaps using str_replace() somehow? Are array keys allowed to have curly brackets within them? Would that cause any problems? Also, I need this to replace the $string value for ALL times these are found, cause it is possible to have the same output desired more than 1 time. For example, if {POST_TITLE} is defined twice it should output the value twice exactly where they have used it at within the string.

Thanks

Answer 1

foreach($defined_vars as $key=>$value) {
  $string = str_replace($key,$value,$string);
}

this is using str_replace like you asked and it is easy to see what is happening. Php also has the strtr or string translate function to do pretty much just this so you could also use

$string = strtr($string,$defined_vars);

but would have to remember what that function does.
